What is the purpose of an OSI model? The purpose of an OSI model is a standard that was created for networks to share information. This standard governs the way information is transmitted over different networks. The model also sets guidelines to those in the manufacturing industry that create and develop software and hardware that are all compatible with each other. This paper will discuss and describe the 7 layers of the Open System Interconnection model (OSI model) and the layers of the Transport

The Physical Data Model (PDM) describes how the information represented in the Logical Data Model is actually implemented‚ how the information-exchange requirements are implemented‚ and how the data entities and their relationships are maintained. There should be a mapping from a given Logical Data Model to the Physical Data Model if both models are used. The form of the Physical Data Model can vary greatly‚ as shown in Figure 31. For some purposes‚ an additional entity-relationship style diagram

Data Link Layer INTRODUCTION: Now a day’s communication is vital for the entire world‚ nothing happens without communication. The cell radio communication and wireless computer networks of GSM (Global System Mobile)‚ CDMA (Code Division Multiple Access) type are worldwide communication systems. All these communication systems are based on the reference model OSI-RM (Open System Interconnection-Reference Model) Description of OSI-RM System: OSI-RM is an International Standard ISO that defines

Physical abuse is the most well known type of abuse. Unlike any other type of abuse‚ there are many indications that physical abuse could be prominent in the child’s life. The first red flag to physical abuse is unexplained bruises. The bruises can be anywhere on the child’s body. If there are bruises that are in the form of an object such as a belt‚ cord‚ or rope‚ this is defiantly an sign that this child is being abused physically. Also if the unexplained bruises happen to appear after an absence

Difference between OSI model and TCP/IP model The Internet Protocol Suite also known as TCP/IP is the set of communications protocols used for the Internet and other similar networks. It is named from two of the most important protocols in it: the Transmission Control Protocol (TCP) and the Internet Protocol (IP)‚ which were the first two networking protocols defined in this standard. IP networking represents a synthesis of several developments that began to evolve in the 1960s and 1970s‚ namely

Crust is the first and upper most layer of the Earth. There is Continental Crust which sits on top of Oceanic Crust. This layer is made frequently from granite rocks and is solid. Continental Crust is approximately 32km. Below the Continental Crust is Oceanic Crust. It is about 8km. This part of the Crust is made from basalt rocks. The Crust is most of lithosphere and is the coolest layer by far. Mantle is like silly putty consistency. It is the largest layer of Earth sitting under the Crust.

BOUNDARY LAYER THEORY INTRODUCTION The concept of boundary layer was 1st introduced by L.Prandtl in 1904. Figure 7-1. Viscous flow around airfoil A structure having a shape that provides lift‚ propulsion‚ stability‚ or directional control in a flying object. Boundary layer is formed whenever there is a relative motion between the boundary and the fluid. Boundary layer thickness: 1. Standard thickness - signified by ‚” it is define as the distance from the boundary layer
